Sometimes your Board can become cluttered of cards, or, if you are using Websites for Trello to host your blog and you write a lot, you'll end up with Lists full of cards, such that you cannot even reach the Add a card button.
In this case you may be tempted to archive your cards, as you would do in a normal Trello Board, but you may be afraid that, by doing it, you'll be hiding the pages corresponding to the hidden cards in your website.
Well, fear no more! Archiving cards doesn't have any effect on your website. You can freely archive any card you want, or all of them, whatever you like.
How can I hide some card/page from my website?
Well, to do that, just prepend a
_ to the name of the card. For more information, refer to the basic Cards documentation.
